What to fix (2)

4 tool definition(s) exceed ~1,200 tokens each (largest: portal_evm_query_transactions, ~1,935).

Move long reference material out of descriptions (link a doc or expose a resource), drop repeated examples, and collapse large enums. Trimming these to ~600 tokens saves ~3,845 tokens every session. How to fix →

Tools: portal_evm_query_transactions, portal_solana_query_instructions, portal_evm_query_logs, portal_evm_get_ohlc · saves ~3,845 tokens/session

Loading this server's tool list costs an agent ~23,240 tokens before any work — more than 95% of MCP servers.

Split rarely-used tools into a separate server or a toolset the client can enable, or expose one "search tools" entry point. Many agents load every connected server's tools into every request. How to fix →

Is the Subsquid Labs Portal MCP server safe to connect to an AI agent?

Glimind scanned all 31 tool definitions for tool-poisoning patterns — hidden or invisible characters, instructions that override the model, concealment from the user, requests to read credential or MCP config files, conversation exfiltration and cross-tool shadowing — and found none. This checks what the server tells the model, not what its code does; review the source before granting access to sensitive data.
